Question

why do ecosystems require continuous input of energy from the sun, and what is the process that converts the suns energy to chimical energy

Answer 1

The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during resp​iration in plants.

Answer 2

Ecosystems require continuous input of the sun's energy, to support the plant life, which feeds the herbivores of that community, and so on throughout the trophic levels. The process that converts the sun's energy to chemical energy is known as photosynthesis.
